it is a little shimmering piece of fresh fecal matter that has hit the floor next to a wet token in the public restroom of an arcade.

oye, man- i was squeezing my buttcheeks together after taking a caca and all of a sudden i saw this golden coin in front of me on the floor- i got up to grab it and then a cacaciel hit the floor man. it looked so shiny there lying next to it- glimmering and wet but you know it was only just a 'cacaciel'.
